[heady iris]

check if those methods are actually being called by adding a Debug.Log to each

[candid coral]

They are called indeed

[heady iris]

Are the methods being called the number of times you expect?

It looks like they're being called once as the objects become non-tracked, then again when they become tracked.

Moving the = true into Start would matter if the Default Observer Event Handler component was calling your methods before Start ran

which is possible

[heady iris]

If they are only being called twice, and the second call sets both variables to true, then it should work fine

Make sure you don't have multiple Object Rotation Manager components in your scene. That could produce confusing logs.

[raven orbit]

Does anyone know why rider generates seemingly weird markdown files?

[candid coral]

I have one component set to the imageTarget of Cube and another to the Cylinder one. So two instances of the script. Is that an issue?

[heady iris]

so you have two Object Rotation Managers?

[candid coral]

One single script, but dragged to both of these

So both ImageTargets have that script

[heady iris]

Those are two completely unrelated components.

They don't know about each other.

Sounds like you want to have one object rotation manager.

[candid coral]

Probably. How do I create a single instace for both of them?

[heady iris]

by only having one component

[candid coral]

You mean, only setting one instance to one ImageTarget? And for the other imageTarget, try to access the instance of this one?

[heady iris]

No. Both of these "Default Observer Event Handler" components should be targeting the same "Object Rotation Manager" component.

One should be calling the SetCylinderInView method and the other should be setting SetCubeInView

[heady iris]

i also noticed that this is calling the wrong method

it calls the Cube method in one place and the Cylinder method in the other

[candid coral]

Oops, missclicked. Changing many things in a short time

[candid coral]

But you are calling the class that way

So no functions can be called

[heady iris]

You have dragged in the script asset itself. Don't do that.

drag in the Object Rotation Manager component that's in your scene

[candid coral]

I am a little bit confused. Where do you mean by scene?

[heady iris]

The hierarchy displays all objects that are in the scene.

Where is your single Object Rotation Manager?

[candid coral]

I am guessing it has to appear in the hierarchy, isn't it

[candid coral]

So I don't have it as of right now

And only have the script in asssets

[heady iris]

It needs to be attached to an object in the hierarchy.

[heady iris]

You already have one attached to an object. You sent a screenshot of it earlier.

[candid coral]

Oh, I get it now. So now that I have attached a single Object Rotation Manager, to the Cube ImageState for example, I can call its functions

But, how do I access to this one from the other ImageTarget (Cylinder one)

I hope I'm understanding it correctly

[heady iris]

just drag in the object with the "Object Rotation Manager" component on it

it can be from a different game object

[candid coral]

I apology for my slowness, I am trying to do that but I can't seem to select the component and drag it onto the other one, since I have to click on the other ImageTarget to open its inspector.

I have tried opening two tabs but they reference the same

[knotty sun]

you dont need to select the component, you can drag the game object that has the component on it and Unity will sort it out

[heady iris]

Drag the game object.

public class BackgroundGen : MonoBehaviour
{
// distance for level to spawn from the player
private const float PlayerDist = 15f;

// object references
[SerializeField] private Transform Background1;
[SerializeField] private Transform BackgroundStart;
[SerializeField] private PlayerLogic player;

// the last end position of the most recent background to spawn
private Vector3 lastEndposition;

// gets player pos
public Vector3 GetPosition() { return transform.position; }

private void Awake()
{
    lastEndposition = BackgroundStart.Find("EndUp").position;
}

private void Update()
{
    if (Vector3.Distance(player.GetPosition(), lastEndposition) < PlayerDist)
    {
        // spawn BG part
        SpawnBGPart();
    }
}

private void SpawnBGPart()
{
    Transform lastBGPartTF = SpawnBackgroundPart(lastEndposition);
    lastEndposition = lastBGPartTF.Find("End").position;
}

private Transform SpawnBackgroundPart(Vector3 spawnPosition)
{
  Transform BackgroundTF = Instantiate(Background1, spawnPosition, Quaternion.identity);
    return BackgroundTF;
}

i got this code from an endless level tutorial as i thought it would work with backgrounds also. my goal is to have backgrounds spawn in all directions. when the player gets a set dist from the last endpoint. but i need it in all directions. how would i go about this. my idea is just to impliement the multiple end points? and ajust the code depending on which direction the player is travelling? but does anyone have any suggestions?

I have a problem with the assets bundle, When i want to create one I got this message:
Moving Temp/unitystream.unity3d to D:/<MyPath>/Assets/AssetBundles/base: Acces refused.

Why is that? I can't find anything online except this post:
https://issuetracker.unity3d.com/issues/building-an-asset-bundle-varient-results-in-an-error-when-there-are-identical-files-at-different-directory-levels

[leaden ice]

Perhaps your application doesn't have access to that path

[pliant spade]

It's the unity application. The path it litteraly the project folder, if the unity app does not have access to it's own folder, what's going on

[leaden ice]

the unity app is not installed in your project folder

you may have put the project folder somewhere it doesn't have full access to

[marsh prawn]

Hey, can inherited functions use extra parameters or can they only use the parameter the base script has ?

[leaden ice]

You cannot change the signature of an overridden method

the signature has to match exactly

it wouldn't make any sense otherwise

how would you possibly call it?

[marsh prawn]

By the new inherited script .-. but yeah its alright

[leaden ice]

But there's no point in inheritance then

inheritance is so other things can call a polymorphic function on a reference of the parent type

[marsh prawn]

I Think i already know how do use it the way I want, so its alright, thanks for the answer and btw just answer the question instead of saying ''what you're saying does not make sense''

[knotty sun]

I don't know why you are quoting, no one said that

[pliant spade]

I moved the entire project folder to the documents folder and still the same issue

[knotty sun]

Are you using OneDrive or somthing similar?

[pliant spade]

For the project or in general?

[knotty sun]

in general

[pliant spade]

I don't use it but i think it's enabled

[knotty sun]

then move your project to a path that OneDrive does not backup

[pliant spade]

Now it's in Documents, and onedrive does not seem to access it. And before it was in another drive and onedrive does not have access to it

[knotty sun]

Documents is backed up by OneDrive

[pliant spade]

It's still happening in another drive tho

[knotty sun]

external USB?

[pliant spade]

Nope

What do you mean? is it on an external usb?

[knotty sun]

so something like D:\Unity

[pliant spade]

Yea

[knotty sun]

but not on an external drive

[pliant spade]

On another internal drive

[knotty sun]

ok, make sure your path has no special characters, only A-Z and 0-9

[pliant spade]

Oh, it have - character

01-Documents

[knotty sun]

Unity can be real finiky about that

[pliant spade]

I'll try to move

Nope this time the path is D:/Work/Project/ and it's still say access refused

[knotty sun]

Have you tried building the bundle to a path outside the project path

[pliant spade]

I found the issue.

I'm building an asset bundle for a DLC, and i named the DLC folder "Base" for the default content. And my asset bundle name was "base", I think it was trying to overrite the folder or something like that.

[knotty sun]

Sounds about right
D:/<MyPath>/Assets/AssetBundles/Base/base

[pliant spade]

Well the bundle was created in AssetBundles path, so at the same level as Base folder

Now that this is solved, do you know if it's the right path to go for DLC?

[knotty sun]

sorry, no idea

[pliant spade]

No problem, thank you!

[jolly stratus]

guys, there is this dotnet folder in my C drive, program files. i was wondering can i just delete this one? it is of 7 gigs and i need some space in C, is this unity related at all? i downloaded android studio quite some time ago could it be because of that? i downloaded it to get the jdk sdk stuff for unity.

[rigid island]

dotnet is related to unity yes

but this seems to be runtime ? or is it sdk

I'm on mac so i forgot where windows saves it, ig Program Files makes sense

I dont recall that being 7gb tho

[pulsar elm]

7gb dotnet folder??

mine is only 740mb

but yes, it's important

but I do not understand as to how many things you got for dotnet that it's that large

[somber nacelle]

the size probably depends on what workloads and versions of dotnet they have installed. for example, mine is nearly 4gb

[rigid island]

first check how many you have installed

dotnet --info (in terminal)

[tall scroll]

so @hidden compass is there a reason you use where T : Singleton<T> ? my monobehaviour one uses where T : MonoBehaviour
Also what's the benefit of making the class abstract again?

[hidden compass]

Using where T : MonoBehaviour allows any MonoBehaviour-based subclass to use the generic class, but it doesn't enforce the Singleton pattern. Without additional checks or logic, multiple instances of the subclass can be created, which goes against the Singleton pattern's intent of having only one instance.

Making the class abstract prevents it from being instantiated directly. This ensures that developers can't create an instance of the abstract class itself, but instead must inherit from it to create singleton instances. This helps enforce the intended usage of the class as a base for creating singleton instances.

[tall scroll]

will fix my stuff then

[rocky basalt]

I feel really dumb, but is there any common reason why the Transform point of child objects don't match the parent transform, even when their local positions are set to (0, 0, 0)?

In my inspector the childs are all zero local, but they're considerable off from the parent transform. I'm perplexed.

An artist I'm working with prob exported these from Blender, if that makes a difference

[hidden compass]

nothing really wrong with the way ur doing it.. but my version just stresses the Singleton pattern a little better

https://gamedev.stackexchange.com/questions/116009/in-unity-how-do-i-correctly-implement-the-singleton-pattern

was my source.. and then i got some help from the beginner channel to help me refine it a bit

[tall scroll]

yeah I just want to make sure what I'm doing is actually correct to the pattern (at least mostly)

if the stuff you said didn't feel like it slightly defeated the point of a singleton I wouldn't fix it

[knotty sun]

Almost definitely the parent or child origin is not where it should be in the model

[rocky basalt]

Sorry, what is 'origin' referring to in that case? Is that something from the 3d model import pipeline?

[hidden compass]

its the origin of the mesh

[knotty sun]

yes, it is the 'center' point of the model

[tall scroll]

(origin/pivot, meaning the specific place in the model that would be at 0,0,0)

[knotty sun]

yes

[rocky basalt]

ohh, so when they set it up in Blender, they did the work "away" from the center origin point?

[zenith bear]

Ok so whenever I try download the xr plugin management it’s always says there s an error so if someone could dm me thanks.

[knotty sun]

yes, they probably 'forgot' to apply the transforms when they exported

[rocky basalt]

thanks for this info. saved me some trouble

[zenith bear]

@knotty sun

May I help

[knotty sun]

May you help what?

[hidden compass]

yeap, for 3D models, its in the modelling software where the pivot/origin is placed

Hey guys, I have this weird issue happening.

I was trying to change some of the quality settings of my mobile build of my game. Originally I changed the quality using Edit > Project Settings > Quality and then I changed the current quality to PC (from mobile)

However as soon as I did this I started having build problems on my physics device. In editor the game works fine, when I build for mobile (iOS) I just get a (somewhat) empty screen completely missing all my assets!

Things I Checked already:

1. Added all scenes to build
2. Rebuild the XCode project
3. Close unity and re-open and then rebuild
4. Changing quality back to mobile

I Really can't get this to build on my phone anymore when I litterally had it working a few hours ago losing my mind over this.

[somber nacelle]

this is a code channel

[clear umbra]

interestingly it flashes pink when I try to load the game, and it shows my line renderer

[clear umbra]

well it is also the code-general channel

[somber nacelle]

yes code-general. because this is a code channel

id:browse to find a channel relevant to your question

[clear umbra]

1. not really helpful, but whatever
2. you can see plenty of people above talking about code-general side of things

[somber nacelle]

please learn to read

[clear umbra]

compiling and building the project can be seen as "related to general coding concepts in unity"

[somber nacelle]

okay then show the code you are having trouble with

[clear umbra]

yeah dude if ur not gonna help, at least dont be toxic lmao

[somber nacelle]

my guy, you were the one arguing about where this question belongs. you should post it in the most relevant channel so you actually get help instead of posting in the wrong channel then bitching that it isn't actually the wrong channel because you didn't bother reading the full name of the channel or its description

[rigid island]

general , as in .. non-beginner code

[clear umbra]

1. Didn't post in the wrong channel I shall remain adamant about that
2. if anything you've completely derailed the conversation here by being extra pedantic about the topic of the channel (which I assure you was on topic)
3. I actually just looked through every other channel and I can't find one thats more suited for the topic at hand.

[somber nacelle]

well if you didn't post in the wrong channel, then share the code you are having trouble with

[naive swallow]

Okay. I believe you that it's on topic.

Now show the !code you need help with

so then what code is that issue related to

[clear umbra]

Technically speaking: Unity C# Compiler Toolchain .NET

[lean sail]

lots of arguing that its relevant to the coding channel, but you called boxfriend toxic when he asked to see code.
There is both #💻┃unity-talk and #📱┃mobile

[clear umbra]

yeah because they obviously had toxic intentions when they asked such a question

oyu can see plenty of people posting in this channel without having SPECIFIC code they are looking at

[lean sail]

so instead of arguing and wasting your own time, why not just post it in the correct channel? This is a waste of everyones time

[naive swallow]

Well if literally anything made in code can be asked here I was wondering if anyone had any tips for beating Hecate in Hades II? I feel like I just literally don't have enough damage, like everything I do is barely making a dent. Do I just need more Arcana?

[somber nacelle]

actually i'd hoped you'd realize you were being ridiculous in insisting that it was a code issue because it wasn't related to code at all

[clear umbra]

Its quite litterally a toolchain issue

[rigid island]

what is a toolchain issue?

[clear umbra]

not to mention the dude before me was asking about transforms and origins, I don't see how THATS a coding issue

[clear umbra]

original issue

[rigid island]

still confused on how changing quality settings would be affecting code at all

this seems related to asset database

I would first try to reimport all Library

[clear umbra]

I was messing with the RP Assets, honestly I'm not sure why it wont render my scene anymore

[clear umbra]

where is this located?

[rigid island]

The Library folder holds all the cache/temp data

its in the project folder

[quartz folio]

To be clear about this: neither of them are, and occasionally non-code questions get answered here mostly because people don't check what channel they are replying in.
Your post is not suited to this channel.

[lament mural]

I'm trying to access the Music folder on my android device to see what files are in there but I can't seem to get it. Anyone know how?

[rigid island]

Don't think unity has built in way to access MediaStore directly

unity does let you call external plugins / code though, i bet you can access native kotlin code like that

[lament mural]

So I'd be relying on reflections?

[rigid island]

I suppose, how expensive can it be anyway? You'd only be getting some paths

[hearty mortar]

So I have a simple input buffering script for processing weapon inputs and handling multi-button chords. It's giving me a NullReferenceException and I don't understand why.

using System.Linq;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.InputSystem;

public class CombatInputBuffer : MonoBehaviour
{
  [SerializeField][Range(0, 1)] private double _chordingTimeout = 0.01;
  [SerializeField][Range(0, 1)] private double _bufferTimeout = 0.1;

  private double _chordingTimer = 0;
  private double _bufferTimer = 0;

  private List<InputAction> _bufferedInput;
  public IReadOnlyList<InputAction> BufferedInput => _bufferedInput;
  private bool _isChording = false;

  void FixedUpdate()
  {
    _chordingTimer -= Time.deltaTime;
    _bufferTimer -= Time.deltaTime;

    if (_isChording && _chordingTimer <= 0)
    {
      CommitChord();
    }

    if (_bufferedInput != null && _bufferTimer <= 0)
    {
      _bufferedInput = null;
    }
  }

  private void CommitChord()
  {
    _isChording = false;
    _bufferTimer = _bufferTimeout;

    Debug.Log("Inputs: "
      + (from action in _bufferedInput select action.name)
        .Aggregate((a, b) => a + ", " + b));
  }

  public void OnInputReceived(InputAction.CallbackContext context)
  {

    if (context.performed)
    {
      if (!_isChording)
      {
        _bufferedInput = new List<InputAction>();
        _chordingTimer = _chordingTimeout;
        _isChording = true;
      }

      if (!_bufferedInput.Contains(context.action))
      {
        _bufferedInput.Add(context.action);
      }
    }
    else if (_isChording
      && context.canceled
      && _bufferedInput.Contains(context.action))
    {
      CommitChord();
    }
  }
}

NullReferenceException is on _bufferedInput

Yet, as far as I can tell, the following intended invariants do seem to be true everywhere which should prevent that:

• _bufferedInput is only ever accessed by the code when _isChording is true.
• When _isChording is set to true, _bufferedInput is initialized to an empty list.
• _bufferedInput is cleared to null on a timer which is longer than the one which sets _isChording to false

[lean sail]

Did you write this code yourself? Throw a debug in that if (!_isChording) and see if its ever even running. Thats the only area where I see you assign something so it wouldnt be null

[hearty mortar]

Yeah, I wrote it myself. I can check, but that's the only place where the _isChording flag is set to true, so how would I be getting the NullReferenceException in the first place if that wasn't running?

[lean sail]

well first thing is you should specify what line the error is actually happening on, the stack trace of it in unity should also tell you when its being called as well. Though really its probably just that _isChording isnt what you think it is at a certain point.

[hearty mortar]

It's happening in like three different places, I'm focused on the invariant violation though, since if the invariants weren't being violated, the error couldn't happen

It's happening on the Debug.Log line (actually an ArgumentNullException, but same thing), and at the contains checks in OnInputReceived

[flint shore]

FixedUpdate is not Update, I haven't trawled your code in detail but are you sure things are being called in the order you expect?

Why not attach the debugger and see...

[somber nacelle]

honestly why even bother creating new instances of the list? just clear the list when you need it to be empty and reuse the same instance

[flint shore]

True that, but the logic error would still exist if there is an expectation of a certain call order.

[lean sail]

i have trouble following this code, but it looks like theres just some random and independent logic happening between the chords and the buffered input. the bufferedInput can just be independently set to null from fixedupdate without care about anything else. then nothings really stopping an NRE from happening like anywhere else

you could also do what boxfriend said, but i suspect theres more issues than just null here. Like it'll probably not be using the correct values if theres already this issue

[hearty mortar]

So, that may not be clear, but _bufferedInput can only be set to null in FixedUpdate when the _bufferTimer expires, which is longer than the _chordingTimer which resets _isChording

... At least, that should be the case, but I added an assertion to that and it's not.

[lean sail]

well its clear that theres an error, where it is null when it shouldnt be. what you wrote is what you assume is happening, the debugger or just simple logs should point you in the right direction

[hearty mortar]

Oh

Doh

[flint shore]

I mean its a fun thought activity to solve the logic error by thinking but if you actually want to fix your problem attach the debugger set the break points and see what is actually happening.

[hearty mortar]

I'm stupid

I forgot to initialize the buffer timer

Or rather, I for some reason initialized it at the end of a chord, not the start

[hearty mortar]

Yeah, I wasn't trying to solve it just by thinking, I was peppering in assertions while we were talking 😅

Ok, I'm confused now. Everything here should be happening in one thread, right? No concurrency?

(NullReferenceException is fixed, but I'm running into a different issue now)

[somber nacelle]

yes, unless you specifically do any multithreading yourself there will not be any multithreading happening on your monobehaviours. and unity messages like FixedUpdate will never be multithreaded

[hearty mortar]

    private void CommitChord()
    {
        Debug.Assert(_bufferedInput != null || !_isChording);
        Debug.Assert(_isChording);

        _isChording = false;

        Debug.Log("Inputs: "
            + (from action in _bufferedInput select action.name)
                .Aggregate((a, b) => a + ", " + b));
    }

How is this getting called twice without that Assertion failing???

[flint shore]

if only someone mentioned using a debugger ...

[hearty mortar]

Ah, correction, the question is "how is the performed event happening twice for a single button press?"

[cosmic rain]

Step with the debugger and you'll figure it out

[flint shore]

A tool that lets you see exactly what gets called when... and the (stack) history of what called it ...

🙂

[cosmic rain]

If you subscribed to it twice for example

[hearty mortar]

I didn't

[flint shore]

Are you sure they are all pointing to the right object?

[hearty mortar]

Yeah, but moreover, it's only getting called twice for "Performed"

Not for "Canceled"

[flint shore]

So step through the darn thing...

[cosmic rain]

I don't see performed or canceled in that screenshot

[flint shore]

That's not stepping through with a debugger.

[hearty mortar]

I'd need to step through the entire input loop wouldn't I?

[cosmic rain]

There's no way we can help you without any context and code.

[lean sail]

you are also calling that functions from other areas like fixed update. this whole thing seems like spaghetti

[cosmic rain]

You can use conditional breakpoints.

[flint shore]

Put a break point on the thing that is getting called twice, look at the call stack.

Lots of options here.

Learning how to use the debugger properly is way more important to your success than solving this one logic error, seems like a good time to do so ... two birds with one stone and all that.

(and yes I know some people go their entire career without using debuggers, but it is the best tool for many jobs, this seems like one of them)

[hearty mortar]

I know how to use a debugger. I was lazy to do so as I don't expect to get relevant information from it here. I know that I'm getting two calls to OnInputReceived for a "performed" event and only one for "canceled," which doesn't line up with my understanding of how the input system works

[flint shore]

you do? 😛

If you have the call stack of whats calling the code you don't expect to be called, its very very likely its going to tell you more than you know now.

[lean sail]

hell, even the stack trace alone from the debug.log should tell you

[hearty mortar]

I mean, yes, but it's going to give me details of Unity internals which I have no clue about, no?

[flint shore]

But set break points on the thing called twice and the place that the flag changes.

[hearty mortar]

Stack trace is identical for both, running off into Unity native immediately

Processing: Weapon 1, Performed
UnityEngine.Debug:Log (object)
CombatInputBuffer:OnInputReceived (UnityEngine.InputSystem.InputAction/CallbackContext) (at Assets/CombatInputBuffer.cs:52)
UnityEngine.InputSystem.LowLevel.NativeInputRuntime/<>c__DisplayClass7_0:<set_onUpdate>b__0 (UnityEngineInternal.Input.NativeInputUpdateType,UnityEngineInternal.Input.NativeInputEventBuffer*)
UnityEngineInternal.Input.NativeInputSystem:NotifyUpdate (UnityEngineInternal.Input.NativeInputUpdateType,intptr) (at /Users/bokken/build/output/unity/unity/Modules/Input/Private/Input.cs:120)

[flint shore]

You can see which bit is happening out of the order you expect, or you can see if you 've got something being called twice you don't expect to be, the point being it will probably tell you something about what is happening.

[hearty mortar]

Like, the key thing I don't understand is, how can I get two performed triggers but only one canceled?

I thought the two have to occur in pairs?

I mean, one is button down, the other is button up?

[cosmic rain]

You can make an educated guess based on the function names.

[lean sail]

did you subscribe the event in code ever?

[hearty mortar]

... It's because I set the button to "PressAndRelease" thinking that that was necessary to send both button down and up

[lean sail]

like some ctx.performed += ...

[flint shore]

Event that is triggered when the action has been started but then canceled before being fully performed.

[hearty mortar]

No, I'm using the Unity editor wiring

The Player Input stuff

[flint shore]

So it is certainly possible to have more performs than cancels.

[hearty mortar]

That said, I think I solved it

[hearty mortar]

This here

[flint shore]

start leads to perform or cancel

[hearty mortar]

TBH, I'm having trouble wrapping my head around the new input system in general. I'm half tempted to just use the old functions for listening to the hardware more directly

But I figure it's important to get this stuff down

[flint shore]

If using the new system you should probably write your own interaction to handle buffering.

[hearty mortar]

How do you mean?

[flint shore]

Implement IInputInteraction to make your buffering part of the system rather than something that sits outside of the system.

I'm guessing at the context of your game, but it seems like what you would want to do is send Performed at the right time.

So your buffer is effectively a custom interactions that knows when a button is down (probably sending Start on press), and if it falls in the allowable buffer/window it sends Performed at the right time (or Cancel if the buffer expires).

[hearty mortar]

So, for starters, I'm trying to set it up so chords can be processed, e.g. pressing A + B at the same time

Also input buffering for chaining attacks, so if you press a button before the cancel window of the attack begins, that input is still around, but that I don't think I can implement within the new input system

I would love it if there's some way to implement the chording within it

[flint shore]

Hmm maybe not ideal then, a fighter probably has too much nuance in the control.

At some level of complexity you would be fighting the system rather than gaining from it.

[hearty mortar]

Yeah, that's what I figured. I'm going to implement the flow as an FSM, I just need to be able to take arbitrary combinations of the three attack inputs

Not actually a fighting game lol, but yeah fighting game style controls. It's a Monster Hunter clone

[flint shore]

Our designers want to take our battles along that Monster Hunter route, I prefer the current system (which is kind of a simple combat which then leads you to an Auto Battler). Reflexes not my thing.

Anyway off topic!

[hearty mortar]

FSM is going to be fun to implement haha. I'm still debating between defining the structure in code or implementing a Graph Tools UI

[flint shore]

Not sure if XNode is still maintained but it was a nice API for very quickly and easily creating custom tree like structure in editor.

[hearty mortar]

Unfortunately looks like no. There is this from Unity themselves: https://github.com/needle-mirror/com.unity.graphtools.foundation/blob/master/README.md

But it also hasn't been updated in 3 years and is still in preview

https://forum.unity.com/threads/graph-tool-foundation.1057667/page-4#post-9647582 Most recent update I can find

[gray mural]

I wouldn't consider this a newbie question. I suppose, this may be achievable by first selecting the InputField's Selectable, then activating the InputField itself. I'm not sure and you gotta check it out.

inputField.Select();
inputField.ActivateInputField();

[jolly stratus]

I see, thx mate.

[merry stream]

anyone know why there is a big delay with my inputs when pressing two different keys? Say I try to press the key 2 and key 3 ability together, only one will trigger. https://gdl.space/opuwitesor.cs

[restive ridge]

I'm making a 3D isometric style game, made pretty much the basic character controller however since the game is isometric, my camera is rotated 45 degrees on the Y, so the player is always moving 45 degrees to the left (45 degrees north west of the camera you could say) how do i make it that when i press W the player moves directly forward of the camera? Code: https://gist.github.com/Winter-r/c023d12a56575925d9a6f3270f92c49a

[gray mural]

Don't you assign a cooldown yourself here?

if (ability.CanActivateAbility())
{
    StartCoroutine(ability.TryActivate());
    OnAbilityUsed?.Raise(new AbilityUse(skillIndex, ability.GetCooldown()));
}

Also, this doesn't make sense. The Action cannot be unsubscribed like like.

abilityAction.action.performed -= ctx =>
    TryUseSkill(Array.IndexOf(
    abilityAction.action.controls.ToArray(), ctx.control));

So have a method which does what you do when subscribing and unsubscribing it

And this is a List, right?

abilityAction.action.controls

You may use the List.IndexOf(this) method instead of the Array.IndexOf

[gray mural]

So you want the player to move in the direction of the camera?

Do it also include rotating the player?

[fathom finch]

Hey guys, I have a script with one function like so:

public IEnumerator Shoot() {
        //If trajectory is even possible, then create the projectile object and apply said trajectory.
        if(GetTrajectory(out Vector2 velocity)) {
            GameObject pj = Instantiate(projectile, transform.position, new Quaternion(0.0f, 0.0f, 0.0f, 0.0f));
            pj.GetComponent<FlyingEnemyBulletBehavior>().parent_flying_enemy_ref = this.gameObject;
            pj.GetComponent<Rigidbody2D>().AddForce(velocity, ForceMode2D.Impulse);
        }
        yield return new WaitForSeconds(launch_rate_seconds);
        has_shot = false;
    }```

Im trying to set a public variable "parent_flying_enemy_ref" inside a script called "FlyingEnemyBulletBehavior", that belongs to the instantiated GameObject variable "pj", via the current script that this function resides in^

for some reason the line

 pj.GetComponent<FlyingEnemyBulletBehavior>().parent_flying_enemy_ref = this.gameObject;

causes the rest of the function to not function

does anyone know why? if I need to provide more code let me know

removing that one line I talked about makes the function work again

[mellow sigil]

In what way does it not work exactly?

[fathom finch]

basically the function spawns a projectile gameobject, which is just a ball, and launches it with a specific velocity

normally this function does exactly that, but with the addition of the line I spoke of, it doesnt create projectile gameobjects and launch them anymore, nothing happens

[mellow sigil]

Add logs after the line to confirm that the code runs, and make sure errors aren't disabled in the console

[fathom finch]

it doesnt, I tried the logs approach

nothing printed

nothing before as well

which is quite confusing

[mellow sigil]

And the logs print if you remove the line?

[fathom finch]

yes, and the function works as expected

[mellow sigil]

the cool down is handled separately, I was talking about the actual key presses from the input system. I had the action map set as button instead of value which was causing the issue. However when I press both keys at the exact same time, only one is registered still. is that a limitation with the input system or am I doing something wrong. I have my action map Skills with binds for 1, 2, 3 etc. Also, I assumed that's how you subscribe for the triggered event, am I mistaken? it works perfectly fine

[fathom finch]

using System.Collections.Generic;

public class FlyingEnemyBulletBehavior : MonoBehaviour

    public GameObject parent_flying_enemy_ref = null;

    // Start is called before the first frame update
    void Start()

[knotty sun]

why are you mixing 2D and 3D components?

ah my mistake

forgot to add the 2D for the rigidbody

but that wouldnt be the issue would it?

🗿

i didnt even attach the script

that im trying to call

thats why it wasnt working @mellow sigil

[gray mural]

• So the message you have isn't printed multiple times? You have mentioned you have bindings. As far as I know, the bindings, which have the keys supposed to be pressed together, should be composite.
• That's not how you usually subscribe to the event. This subscribes to the event, yes, but using this kind of subscription makes you unable to unsubscribe from this event.

[mellow sigil]

So did you have errors hidden or why didn't you see the NRE error?

[fathom finch]

there was an NRE error, I missed it as I looked though the logs

😔

silly old me

thank you for helping though

[boreal condor]

hey there I'm wondering if anyone can help me think a solution for dragging a rigidbody from a pivot point instead of its center, my method works but positions are kinda odd when the object rotates, I need a second brain im almost suffering
Here's some relevant code

// This line is inside a method
_grabbingBody.AddForceAtPosition(
                GrabDirectionTowardsCursor() * grabForceMultiplier,
                GrabPointTransformed()
            );
// ===================== FUNCTIONS & HELPERS ============================
public Vector2 GrabPointTransformed()
{
    return _grabbingBody.transform.position + _grabbingBody.transform.TransformDirection(_objectGrabPointPivot);
}

public Vector2 GrabDirectionTowardsCursor()
{
    return (PlayerCursorAttachment.CursorPosition() - GrabPointTransformed());
}
// This is what I do when left click is pressed, CursorPosition() is the position of the yellow eye sprite (which is another GameObject that acts as a cursor)
_objectGrabPointPivot = PlayerCursorAttachment.CursorPosition() - _grabbingBody.position;
_initialGrabPoint = PlayerCursorAttachment.CursorPosition();

[latent latch]

Maybe use transform point then make a direction using world coordinates?

Actually, I don't think you need local coordinates. Just a position here with world coordinates

[boreal condor]

I'm actually confused about how AddForceAtPosition handles the given position

I'll read the docs maybe I missed something

[latent latch]

I assume the problem is the arm is going further from the point you clicked, right?

So the question is, does the location you click give the correct coordinates or is it another issue because I'm not too sure of the requirements here.

[boreal condor]

yes, it changes depending on the rotation, like if it rotates 90 degress it still tries to grab the bottom part but from its own coordinates or something like that, I mean it makes sense if I used TransformDirection but can't think of anything else, 'cause most attempts made the body rotate like crazy lol

[boreal condor]

the coordinates of the click are accurate because I'm using a gameobject as a "fake" cursor, so it has the position properties

[latent latch]

TransformDirection and TransformPoint deals with local position such that the object is a child to another, and you want to convert the local position relative to the parent as world coordinates

[boreal condor]

the hand is only visual, it moves to where the resulting position is, pretty much the offset between the box and the click

[latent latch]

But, if used on an object not a child, I don't believe it does anything besides returning world coordinates

Ah, actually maybe im confusing myself. You would just grab the local coordinates via transform.local otherwise, so the method is useful to get relative coordinates without having them actually be child/parent.

    void Start()
    {
        // Instantiate an object to the right of the current object
        thePosition = transform.TransformPoint(Vector3.right * 2);
        Instantiate(someObject, thePosition, someObject.transform.rotation);
    }

Right, so say you want to always get a unit that's always on the right side of the object, you could use this method.

and you have InverseTransformPoint where you can get the exact local* coordinates of that position in space that's relative to another transform without having to child it.

[boreal condor]

TransformPoint is the equivalent to what I was doing before?
_grabbingBody.transform.position + _grabbingBody.transform.TransformDirection(_objectGrabPointPivot)

[latent latch]

what space is _objectGrabPointPivot in?

[boreal condor]

wdym by space?

[latent latch]

wait, you're using TransformDirection here with a position vector

[boreal condor]

yeah, that position is the pivot from where I want to drag, I'm making small changes to see what improves its behaviour

[latent latch]

is playercursorattachment using ScreenToWorld?

[boreal condor]

No

[latent latch]

What's the returned value of it then?

[boreal condor]

the objects position lol

    public static Vector2 CursorPosition()
    {
        return Instance.cursorTarget.position;
    }

Im not using positions provided by the mouse

so the cursor pretty much lives in the game's world

[latent latch]

I'm trying to figure out why you don't just use world positions for everything. Wherever this cursor is, just grab the transform.position, and if you need a direction from the target (cursor position) minus the player position

[boreal condor]

I need to somehow keep _objectGrabPivotPoint attached to the objects rotation AFTER it has been grabbed, but otherwise use the cursor position no matter the rotation, I am not sure why am I failing on that last step

[latent latch]

Oh, but the hand sticks to the point of the object, so there is some locality with the object going on i guess.

[boreal condor]

My math is most likely wrong but unsure where

[latent latch]

It makes sence of what you're trying to do because you are holding onto that item without childing the hand to the object, so yeah these methods would be helpful.

So the problem here is where you click, you want to cache a local point onto that object you are holding.

[boreal condor]

the red line represents the correct place where I want to drag from, so perhaps I'm doing wrong modifications to _objectGrabPointPivot after it has been set with the correct values

[latent latch]

https://docs.unity3d.com/ScriptReference/Transform.InverseTransformPoint.html
It may be this method you're looking for

world position to local relative to the box's position

[boreal condor]

tried using it and made everything fly, I'll read what it does exactly

how would you use it?

[latent latch]

boxTransform.InverseTransformPosition(cursorWorldPosition)

this would give you the local point on the box from where you click

[boreal condor]

bugs are fun

[latent latch]

Well, when you get the local point, and you want the hand to go to that point in world coordinates, then you would use :

Transform.TransformPoint
https://docs.unity3d.com/ScriptReference/Transform.TransformPoint.html

[boreal condor]

oops i used the wrong method my bad

[latent latch]

so basically, cache the point when you click, and every frame afterwards if you want the hand to go to that position (or using some force method). You would use boxTransform.TransformPoint(cacheLocalPosition) to get a world point

so now you can devise a direction such that:
boxPointWorldPosition - handWorldPosition = direction

[boreal condor]

transformpoint behaves exactly as my previous method so, good thing I learned about this one at least yet the issue regarding the box rotation is still present, I'll turn it into a sprite with visible directions maybe it helps a little more

[novel bough]

@fervent furnace thanks for your wonderful explanation, I saw that you've been typing for so long!😇

[latent latch]

transform.TransformDirection is useful too, but what I can make out of your code is you're using a point for the parameters when it expects a direction

or maybe I am misunderstanding what that variable may be

[normal wharf]

I'm struggling to design how I want to handle data exactly in my project. I'm trying to design a simple RPG skillset, and this is what I've come up with so far:
A MasterAttribute script, which I then generate gameobjects off, for the actual skills, they look like the attached pic.
A manager script to create a defined sized array, then populate it

What I'm confused about is; In my own design I don't know how you would interact with the gameobjects (the attributes), but also with a player + enemies, how would I manage their attributes as well, seperately?

I am trying to plan a modular system that could be used for various data like currencies, stats, etc that can be extended in the specific items if needed.
Image

Just looking for advice, this seems like a bad approach, but everything else I've seen is too simple, or hard coded...

[latent latch]

I would debug to make sure that the point you're getting with InversePoint is correct. Ideally, click the top left corner of the box each time and flip it, then try again in that same position. The values should always be different each time you flip it.

[latent latch]

now, pass that point back into TransformPoint and do the same method of debugging similarly, but this time you should get a world position which is always the same

[boreal condor]

so what I'm understanding by changing the sprite is that it attempts to use the world Y position as the object's Y relative position

[latent latch]

what's happening here is that when you click the left of the box in world coordinates, it's translating to left of the box in its local coordinates

[boreal condor]

yeah its pretty much expected, howeverrr using global coordinates directly causes conflicts, i'll do changes and show what happens exactly

[latent latch]

using inversePosition, this position in world coordinates should always become a position in local coordinates as to where you click

[latent latch]

Better to question why you need to make each stat modular in design? Does every entity not have Agility?

[normal wharf]

Well, my thought was that npc's and players would potentially, but there might not be enemies that would have it. That idea then sprouted into; how can I drop in/drop out the stats

It just seemed like that would be a more robust system (Which I'd like to design)

[latent latch]

That's fine, the only problem I can see is that you have to consider formulas later on as if you were to say attack someone and agility represents their chance to dodge, how will you handle those without agility? You would have to always check what you are attacking has agility, and if they don't then fall back onto another method.

[boreal condor]

Dragging rigidbody from Point

[normal wharf]

This is the precise thing I thought of when I realised my system was flawed, haha...

That IS something I'd like to do, e.g. weapon type, armour type etc.

But I realised my base design is too pidgeon holed, I just don't know what a good way of doing it is, am open to suggestions 😦

[latent latch]

I've made stat systems such that if they are a caster then they have stats related to casting. They have spell damage, Mana, spell range, ect. But, when it comes to base stats like defenses, usually all my entities had it.

Interfaces like ICaster, IMelee, IRanger

otherwise I'd just give everything stats so I wouldn't have to fallback onto scenarios where they didn't have stats to compare against.

[normal wharf]

I did think interfacing might be a good way to handle it, but would you just have a script for each stat, and then that manages interactions that way?

Also; How do you assign that status to say, an entity? With a manager script

This is where my understanding is failing I think

The data structures i'm fine with, I just don't even have examples of these interacting with eachother

[latent latch]

Well, first off I'd make an SO for each enemy and assign what they can do. Your method with this design would be composed of a list of stats each of these entities would have. My method of grouping stats a bit more would be a few fields that detail that if they are a caster I would assign a struct/class of stats relating to that.

[Flags]
public enum Affinities
{
    None = 0,
    Caster = 1 << 0,
    Melee = 1 << 1,
    Ranger = 1 << 2,
}

public class EnemySO : EntitySO
{
  [field: SerializeField] public Affinities Affinities {get; private set;}
  [field: SerializeField] public BaseStats BaseStats {get; private set;}

  //Offensive Stats
  [field: SerializeField] public CasterStats CasterStats {get; private set;}
  [field: SerializeField] public MeleeStats MeleeStats {get; private set;}
  [field: SerializeField] public RangeStats RangeStats {get; private set;}
}```

[normal wharf]

Ah, I see

Each of these being their own script with itneraction code, like you mentioned right?

Or are they lists which you set in each entity? because isn't that frequently re-used, even if just interfaces?

[latent latch]

[Serializable]
public class CasterStats
{
  public float SpellDamage;
  public float CastSpeed;
  public float Mana;
}```

Ah, I was going to suggest to check if these classes are null, but Unity will always create them regardless if you edit their instance in the editor, so what you can do is have flags or my preferred way of doing it with a flag enum

[normal wharf]

Gotcha, thanks for the examples!!

This gives me a few ideas 🙂

[latent latch]

[Flags]
public enum EntityAffinities
{
    None = 0,
    Caster = 1 << 0,
    Melee = 1 << 1,
    Ranger = 1 << 2,
}```

if(EnemySO.EntityAffinities.HasFlag(EntityAffinities.Caster))

There is support for them in the inspector which is surprising.

[normal wharf]

Flags? Very cool

Maths question - has anyone done ellipse to ellipse intersection tests?! I am struggling to find C# code, I could use a general intersection maths library

[vagrant blade]

I know Freya has a math one, not sure if it contains what you need though. Can check it out

[placid summit]

Nice, I think she skipped Ellipses though!

[placid summit]

I think they may be missing rotation there which is my unfortunate need. I shall find it but it may be over complicated!

math.stackexchange.com looks very useful, unfortunately my understanding of equations is not amazing

seems you make one a circle and... https://math.stackexchange.com/questions/864070/how-to-determine-if-two-ellipse-have-at-least-one-intersection-point

but converting equations to C# is a problem for me!

hmm seems an n sided polygon might be the reasonable maths fix rather than such accuracy

[tight goblet]

Hey there mates, Im trying to cull particle system when offscreen, all is setup as recommended, but still not working (the PS still running even when cam is not showing the object):

[late lion]

The scene camera counts as a camera in this scenario, so you can't observe the pausing directly.

[magic harness]

Hey guys, quick question. I'm using the navmesh system to move my player, and i did the boot logic for my game in a way where i create my player in a different scene from where my gameplay actually happens.

So.. there is no navmesh whenever i create my PlayerCharacter, how can i go around that problem?

[tight goblet]

Oh, so there is no way to observe the culling effect?

[late lion]

Not directly, but depending on what your particles are doing, you should be able to see that it is in fact paused while you're not looking at them.

[tight goblet]

through script and log?

[late lion]

If you have a particle system that is a burst emission that goes off every 5 seconds, and you look away right as a burst starts, wait 2 seconds and then look back, you should see that the same burst is still finishing, even though it should have finished in those 2 seconds.

[tight goblet]

Oh gotcha! Nice nickname btw, thats rare, lol

[tight goblet]

But through log it seems to be playing even off playmode cam/scene cam 😦

[late lion]

I don't think that property reflects whether it's paused from the culling mode. That's separate.

[tight goblet]

When it is doing culling, it doesnt pauses the ps ?

I did that:

if (_particleSystemOne.isPlaying)
{
    Debug.Log(gameObject.transform.parent +" - "+ _particleSystemOne + " - is playing");
}

there is a way to check if culling is working through script?

[late lion]

Are you just doing this temporarily to make sure it's actually working, or do you need this to make your game work?

You can check if the renderer is visible through ParticleSystemRenderer.isVisible. Or you can check if ParticleSystem.time is still increasing. If you have the culling mode set to Pause, the time should stop. If it's set to PauseAndCatchup, it might either just keep going or pause and then jump when visible again.

Hello!

I have a base abstract class Fruit.
I have children classes, Apple, Banana and Orange, each with different parameters to change.

I want an editor that can select one of the children classes of Banana from a dropdown and use that class's field editor.

For example, I have a List<Fruit> fruits, and in the editor I add a new element. It shows a dropdown, and once I select class Banana, it allows me to change the parameters of that Bananaobject; when I find it on the code, I can cast that Fruit object to Banana and use its parameters.

How would I do this?

Cannot implicitly convert type 'tile' to 'Tile'

but will figure it out thanks

[rigid island]

seems you're mixing a custom Tile with Unity's Tile

[leaden ice]

Looks like tileprefab is tile but you're trying to put it in a Tile variable

[candid elm]

did you make 2 different tile classes

[leaden ice]

this is clearly telling you the problem!

[hardy barn]

ye ye

thanks

[rigid island]

I would step through code to see if this is being called right after

[candid elm]

in the update it checks for the nearest interactable object and in the second method it decides whether to activate the object or not

would doing some async magic solve things

if i manually activate the interactable then walk away, it naturally fades away

the fade away works

just not the appearing

[rigid island]

the fact that its in Update is a little worrysome

[candid elm]

i think that might be the issue

idk how to do it otherwise

[rigid island]

code doesn't lie, if its staying inactive it is constantly setting to active-false

[candid elm]

i made debug logs and all of them work fine

[rigid island]

can you send the part on how you find interactable in the first place ?

[candid elm]

ok
second pic is for the interactable class
basically if the player is near it
it added itself to the list containing all near objects to the player
then the player class does the maths and finds the closest one

i didnt use overlapsphere to save some performance i think

first pic is how to find the closest interactable

[rigid island]

the FadeAway part is fine, its the conditions that call it that arent

[candid elm]

the second part might be some spaghetti coding

[candid elm]

do you have any suggestions

ill try doing async black magic otherwise

[rigid island]

don't think async would change much here except add more complexity where it doesn't need to be

[candid elm]

btw theres a single bool controlling the popup in the interact ui class

if object is activated once
bool becomes true
cant activate again

[rigid island]

you need to find the condition to reset the whole system, I usually do a raycast so typically in the else statement is where I put it, but since here its a distance check its a bit more tricky

[candid elm]

only by disabling the ui can you reactivate

[candid elm]

the distance check works very fine

[vast patrol]

woah that image already tells everything about curves

[rigid island]

yeah I understand that part, I'm just wondering, which condition you want so it is no longer interacted with

[vast patrol]

just increasing point on first line and second line by same % right

[candid elm]

when theres no more item near you (no more interactables in the list), the object fades away

[rigid island]

why not put the fade there then ? but only do it if there was interactor in the first place

like here

I see you tried something like that here already

[candid elm]

ill retry that

[rigid island]

what was wrong with it

[candid elm]

i forgor

[rigid island]

just make sure you check if interactor is not null

[candid elm]

ah yes the issue was that in the second method which decides whether to show the ui or not there were some conflicts

ill try tweaking it

[candid elm]

if interactor is null we exit the function

so everything below that line of code is the else statement basically

[rigid island]

dont need to exit the whole thing, just the part of the UI. the return is fine, just put FadeOut inside the if interactor is not nulll

[vague surge]

Not sure if this question should be here or in #archived-code-advanced,
I have a modual avatar that i'm merging at runtime into a singular skinned mesh. the outcome mesh looks fine but it does not render in unity.
what would be your starting point to investigate the issue? I am starting from a new mesh() so i might be missing some default setting

[candid elm]

oh youre talking about the ui?

[rigid island]

the Popup right?

[candid elm]

yes

[rigid island]

yea DeactiveInteractorUI

[candid elm]

nothing changed unfortunately

if i deactivate all codes for the fadeout

the appear works again

lol

but i dont know where the contradiction in my code is

[rigid island]

DeactivateInteractorUI being in Update

probably

[candid elm]

where can i put it

[rigid island]

just remove it

call it manually if the count ==0 && is active

[hardy barn]

yo , have no clue on how to do that any helpp?

tried fix that

[candid elm]

technically that would be still called in update?

[hardy barn]

i cant

[candid elm]

if its inside a method thats called in update

[rigid island]

thats why Im saying remove it from Update you dont need it

[hardy barn]

all the code
using System.Collections;
using System.Collections.Generic;
using TMPro;
using UnityEngine;
using UnityEngine.UIElements;

public class Tile : MonoBehaviour
{
public Tile state {get; private set;}

public tillcell cell {get; private set;}

public int number {get; private set; }

private Image background;

private TextMeshProUGUI text;

private void Awake()
{
    background = GetComponent<Image>();
    text = GetComponent<TextMeshProUGUI>();

}
public void Setstate( Tilestate state , int number)
{
    this.state = state;
    this.number = number;

}

}

tilestate CLASS

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
[CreateAssetMenu(menuName = "tile")]

public class Tilestate : ScriptableObject
{
public Color backroundcolor;

public Color textColor;

}

[leaden ice]

use the correct type for your variable

[candid elm]

do you have any example

[rigid island]

big reason you should not Name classes the same names as Unity classes 😛

its confusing you and your IDE (code editor)

[hardy barn]

ye ye

so change class names

[leaden ice]

Why are you posting this code that has nothing to do with the error

[hardy barn]

have no idea how to fix that

im dumb af

idk

[candid elm]

knowing if the count is 0 would require an update wont it?

[rigid island]

in a distance check, correct

but ideally you would only run it once, since you only have closestInteractor once

[candid elm]

closestinteractor dynamically changes

[rigid island]

also. you should store these inside a variable, especially if you need to use it more than once

[candid elm]

youre right

[leaden ice]

you're overcomplicating it. @hardy barn

You have:

B thing = whatever;
A otherThing = thing;```
You can't store a B in an A variable.
You would need:
```cs
B thing = whatever;
B otherThing = thing;```

[vast patrol]

no wait also curved line goes under the percentage

[rigid island]

it changes but its either null or not null

so you're only fading if its not null and count is 0

[candid elm]

so the null check is not necessary and i can only rely on the count?

[rigid island]

null check is useful so you dont try to fade something that isn't there

since it occurs every frame and == 0

[candid elm]

ah
closestinteractable is not UI
its an object that you can interact with

my naming convention is kinda bad

[rigid island]

thats not what pops the UI ?

[candid elm]

the UI itself is a singleton instance

[candid elm]

closestInteractable is the closest interactable object to the player,

InteractorUIManager handles the worldspace canvas higlighted in red

[rigid island]

those are the ones not popping up because ur hiding the UI everyframe

did i understand that?

[candid elm]

it only hides the ui when theres no object

ill do a little tweak brb

[rigid island]

oh now Im confused so thats working fine?

but what isn't

[candid elm]

the fading out works fine but fadein doesnt

thats the only issue

it doesnt fade in technically it just gets set active

i plan to tween it when it actually works

[rigid island]

ok but its not being active because the setting to active false is running every frame yes?

so the problem is SetActive(false) running everyframe

[candid elm]

i made a bool switch so getactive doesnt get triggered every frame

[candid elm]

it only gets setactive false when the list is empty

and the debug logs prove that

my theory is that the update is so fast that it gets triggered before the first check idk

[rigid island]

quite possibly

[candid elm]

this is why im thinking of using an async method

that waits after the distance check to execute the second method of showing the ui

@rigid islandnvm i fixed it

literally all i did

was remove 1 bool

LOL

[rigid island]

which one is that

was just typing something about it

curious if it was related

[candid elm]

i used the bool bcs

i didnt want the tween to be called more than once

as u can see in the commented tween part

this is a nightmare for me

[rigid island]

ohhh

[candid elm]

do u know how to properly do it with tweening

[rigid island]

you're talking about DOMove part?

[candid elm]

yep

[rigid island]

You could potential make a bool that gets back to false when the tween is comeplete

kinda how you had it before commenting

[candid elm]

i have an idea of how ill try it

[rigid island]

you can use the same way with the lambda function but with a bool

the OnComplete part

[candid elm]

ok i finished writing it ill try it

oops

[rigid island]

shouldn't that be !haspoppedUp

[candid elm]

its supposed to be if (!haspoppedup)

[candid elm]

yes youre right

[candid elm]

the tweening words but only when i go far from the object

[rigid island]

distance check conditions?

[candid elm]

dont think its related to that

nvm im stupid

[rigid island]

what was it ?

[candid elm]

i forgot that i put a resetter here that resets the value of haspopped up to false

[rigid island]

Ahhh

[candid elm]

in the end it still only appeared when i got far from the object

and i accidentaly crashed my unity trying to fix with a while loop

wild

[rigid island]

yeah while loops can do that easily lol

[candid elm]

tweening is the most rage inducing thing 4 me

[inland pawn]

Hello! I'm having some problems with a glitchy rigidbody that I'm trying to move... It's like jittering everytime move the player, altrough the player doesn't seem to be jittering when comparing to the background. The jittering only occurs when walking, not when looking around so that the object follows. I'm kinda out of ideas as for what could be the problem, so all help is appreciated!

Here's the logic for walking:

void Update()
{
    float x = Input.GetAxis("Horizontal");
    float z = Input.GetAxis("Vertical");

    direction = Vector3.zero;
    direction = (transform.right * x + transform.forward * z).normalized * speed;

    if (controller.isGrounded)
    {
        yVelocity = 0;
        if (Input.GetButtonDown("Jump"))
        {
            yVelocity = jumpForce;
        }
    }

    yVelocity += gravity * Time.deltaTime;
    direction.y = yVelocity;

    controller.Move(direction * Time.deltaTime);
}

And the logic for making the cube follow the crosshair when picking it up:

public void Update(){
    if (isInteracitng)
    {
        pickupPoint = Camera.main.transform.position + Camera.main.transform.forward * pickedUpDistance - pickupOffset;
        rb.velocity = Vector3.SmoothDamp(rb.velocity, (pickupPoint - transform.position) * smoothForce, ref refVelocity, smoothTime);
    }

}

Also a video demonstrating the problem:

[candid elm]

did you try putting it in the fixedupdate method

[rigid island]

^^ ideally you want to move rigidbodies in FixedUpdate

Input should however be captured in Update

[inland pawn]

Tried now, still doesn't fix it...

[rigid island]

also is Interpolation on

[candid elm]

i think it might be related to the smoothtime in the smoothdamp?

[rigid island]

more than likely is physics rigidbodies move at FixedUpdate and CharacterController is moved on Update

[inland pawn]

That seems to have fixed it, thanks!

[candid elm]

uhhhhhh
how do i fix this

is this how you store a dotween action in a variable

[rigid island]

i believe Tween is the type yes

https://dotween.demigiant.com/getstarted.php
had to double check

[candid elm]

what could be a reason for killing the tween

[rigid island]

I haven't explored dotween too much, i'm gonna assume its kind of like Coroutine?

maybe the object was disabled/destroyed or Timescale?

[candid elm]

nah the object is still in the hierarchy and the timescale is 1

[candid elm]

i fixed it by adding this lol im stupid

now it works FINALLY

after 3 days

thanks

[rigid island]

nicee catch!

[merry stream]

https://gdl.space/uqonogehek.cs is this the right way to use the new input system? I seem to be having issues when pressing two of the same keys at once.

[leaden ice]

No

First off - #🖱️┃input-system

[merry stream]

well its a code question

mainly

[leaden ice]

but this is a rabbit hole I've been down many times, and trust me it's 10x simpler if you just make 10 separate actions

Skill1
Skill2 etc

[merry stream]

ah okay

so dont have everything on one map

then have 10 references in the code?

[leaden ice]

Look how world of warcraft does it

imagine writing code to make this UI

With 10 actions, much easier

[merry stream]

alright

[leaden ice]

Depends which workflow you're using but like

InputActionReference[]``` works

[merry stream]

check the code to see

ah okay, then just index by which button

also, is action type "value" and control type "any" for something like this?

[leaden ice]

Why not Button

[merry stream]

no clue

[leaden ice]

Again I'm recommending making 10 separate actions, each one a regular Button action

[merry stream]

kk

[merry stream]

also, is the OnEnable and OnDisable correct? it works but seems kinda messy

[leaden ice]

Not sure what you mean by that

[merry stream]

in the code

is it correct to
//abilityAction.action.Enable();
//abilityAction.action.performed += ctx => TryUseSkill(Array.IndexOf(controls, ctx.control));

[leaden ice]

You'd have to be more specific. There are many ways to use the input system

[merry stream]

im going to change the index stuff

is that the correct way to subscribe and do I need to enable/disable

someone was saying earlier that its wrong

even though it works

[leaden ice]

sure - if you use an array you can do like:

for (int i = 0; i < abilityActions.Length; i++) {
  int actionNumber = i;
  abilityActions[i].action.performed += ctx => TryUseSkill(actionNumber);
}```

[leaden ice]

If you want to unsubscribe you just can't use a lambda

[merry stream]

is it necessary to unsubscribe?

[leaden ice]

That depends on whether the subscriber of the action has a shorter lifespan than the action asset itself

[merry stream]

okay, so just to keep it clean, i dont use a lambda and instead subscribe/unsubscribe with a for loop

[leaden ice]

I don't thnik those are mutually exclusive

[merry stream]

"If you want to unsubscribe you just can't use a lambda" am I misinterpreting?

since I am doing it in array, i dont need the ctx

[leaden ice]

well you either need an actual function (per action) or you need to store the lambdas in an array for later unsubscribing

[leaden ice]

True but you need the actionNumber

[merry stream]

which is just the index

[leaden ice]

Sure but you can't pass that index into the function without a lambda or something else

[gray mural]

Right, that's what I have told you yesterday

[merry stream]

ah yeah

[gray mural]

You will have to subscribe it to an actual method without adding the additional parameters

onSomethingHappenning += YourMethod;

onSomethingHappenning -= YourMethod;

[merry stream]

yeah, do you recommend making methods for each skill or leaving it how it is? also, do I need to enable/disable the action as well ie abilityActions[i].action.Enable();

[leaden ice]

You can do something like:

Action<CallbackContext>[] lambdas = new[10];

// subcribe:
for (int i = 0; i < abilityActions.Length; i++) {
  int actionNumber = i;
  lambdas[i] = ctx => TryUseSkill(actionNumber);
  abilityActions[i].action.performed += lambdas[i];
}

// unsub:
for (int i = 0; i < abilityActions.Length; i++) {
  abilityActions[i].action.performed -= lambdas[i];
}```

[leaden ice]

you can do it that way or just enable the whole action map

btw yes the "actionNumber" thing is necessary due to lambda variable capture

[gray mural]

You may disable an action if it shouldn't be invoked

[merry stream]

    private void OnEnable()
    {
        for (int i = 0; i < abilityActions.Length; i++)
        {
            abilityActions[i].action.Enable();
            int actionNumber = i;
            lambdas[i] = ctx => TryUseSkill(actionNumber);
            abilityActions[i].action.performed += lambdas[i];
        }
    }

    private void OnDisable()
    {
        for (int i = 0; i < abilityActions.Length; i++)
        {
            abilityActions[i].action.Disable();
            abilityActions[i].action.performed -= lambdas[i];
        }
    }

look good?

[gray mural]

Looking fine to me, but actionNumber is not necessary if it simply equals to i

[leaden ice]

actionNumber is necessary

otherwise you'll get lambda variable capture on the i variable

and all of your actions will act as if they use the skill at abilityActions.Length

[gray mural]

Oh, right

[chrome berry]

And that's a fun bug to figure out down the road when it breaks 😄

[naive swallow]

My nemesis, Lambda Capture

[chilly surge]

Oh what a coincidence that I was just talking in #archived-code-advanced earlier about reactivity systems having the ability to automatically unsubscribe, and the internal mechanism essentially boils down to the exact same code.

[gray mural]

I remember having the same bug almost a year ago. And now I'm telling them to get it too, haven't learned from the mistakes

[merry stream]

is there a way within the input asset to make it repeat while held or do I just handle that in code?

[leaden ice]

handle it in code

[merry stream]

what method would I subscribe to?

isPressed?

[gray mural]

Are you using the new input system?

[merry stream]

yes

[chrome berry]

Are you using C# events?

[merry stream]

https://gdl.space/asibosixuw.cs

[gray mural]

performed is invoked in Update every time the value gets changed

[gray mural]

They're using new Input System's actions

[chrome berry]

Yup, which are c#, rather than unityevents off of playerinput component. Just wanted to be sure

[leaden ice]

only when the value is changed

[leaden ice]

void Update() {
  if (myInputAction.IsPressed()) DoSomething();
}```

[gray mural]

Right, what have I said?

[merry stream]

wont that double press when I press once though?

[chrome berry]

The way I did it was with an internal timer started with on performed, and then incremented and checked either in update or in a coroutine or unitask

[latent latch]

'new' input system doesn't have continuous callback so that would require to poll that input unfortunately

[unique ivy]

From the api

[leaden ice]

You said you wanted to do something every frame

Yes this is the way^^ those are like GetButton GetButtonDown, GetButtonUp

[gray mural]

performed is a continuous callback

[leaden ice]

it only happens when the control actuation changes

[latent latch]

that's just that frame, no?

[leaden ice]

if we're talking about a button, it's only when the button is pressed

if it's a joystick it's when the joystick changes actuation. It's not every frame.

[gray mural]

It is called every time the value is changed

[latent latch]

I know you can boolean continous callback though for when you pressed or release

[chrome berry]

on performed only gives continuous input if it's on a vector2 like a joystick and you don't keep it perfectly still

[unique ivy]

You can check the context value of button type and while it’s = to 1 do action

[leaden ice]

yep if you're just holding the joystick to the right, you won't get a performed each frame

full stop if you need to do something every frame you should be using Update

[merry stream]

so i could just get rid of the subscribing and what not and just loop checking for IsPressed

    private void Update()
    { 
        for (int i = 0; i < abilityActions.Length; i++)
        {
            if (abilityActions[i].action.IsPressed())
            {
                TryUseSkill(i);
            }
        }
    }

[leaden ice]

yes

you could do that

[gray mural]

Having a WASD movement also calls it multiple times when the direction gets changed from (1, 1) -> (-1, 1) -> (0, 1)

[chrome berry]

I should update my central input handling class for held down buttons. I think I'll have other classes subscribe with an action to call whenever the designated button is kept held down for a minimum of X seconds, and then retriggered every Y seconds after

[leaden ice]

but you probably want WasPressedThisFrame() no?

unless you want TryUseSkill to happen every frame

[merry stream]

hm, should I centralize input and have other classes just access that

[merry stream]

ideally I want it to get pressed once when pressed, then after a short delay, repeated every frame

[chrome berry]

It depends how many other classes you have asking for input. If it's just a player controller and maybe one menu system, then probably not. If you got lots of different classes wanting input then centralizing it can save a lot of work

[merry stream]

similar to holding a key while typing

[merry stream]

okay, ill keep that in mind

[chrome berry]

One other benefit is that if you're doing lots of clean up or processing of the raw input before using it, then a central class can unify that all in one place
Or for things like a fighting game where inputs get parsed for special moves and you'd likely want that figured out in one spot, rather than your fireball code doing the work and then your piledriver code doing the exact same work, etc.

[merry stream]

okay, its not going to be too complex so I don't think it's needed

[chrome berry]

It's not something that's too difficult to refactor into a single class, if you do find you need it, so no need to worry and do it prematurely

[light pond]

how can i approach this with scriptable objects

[leaden ice]

SOmething like:

public class Number : ScriptableObject {
  public int val;
}

public class Addition : MonoBehaviour {
  public Number a;
  public Number b;

  public int CalculateResult() {
    return a.val + b.val;
  }
}```?

unclear what you mean beyond this

[light pond]

i want something like a drop box for the sprite and this for the same time

like number A

[chrome berry]

So in game you drag one of those number blocks into the formula and it calculates it?

[light pond]

its like a crafting system but u just click a button

u dont drag in anything

[chrome berry]

Got it, you select the A you want, the B you want, and C changes

So the blocks wouldn't be numbers, but some kind of ingredient, item, resource, etc.
So you'd probably make a scriptable object that stores the data of those things
Another class for the clickable option that references which scriptable object is the data for it
And finally some overall class that tracks what options have been picked and determines the result once A and B are selected

Oh and probably a recipe class as a scriptable object which has references to A and B, and the C you get as a result
So that last class above goes through the list of recipes it has and finds the matching one to find C

[lone musk]

Hi i am helping make a tool that allow people to cad robots spesificly for the vex robotics compation and we want to add a feature which would allow people to import diffrent 3d models for stuff like custom plastic parts and stuff like that, how would i go about doing that?

[heady iris]

importing models at runtime, not in-editor, right?

[lone musk]

ya

[heady iris]

for glTF, there's https://docs.unity3d.com/Packages/com.unity.cloud.gltfast@5.2/

Not sure about FBX.

[lone musk]

anything for obj?

[wraith cobalt]

There are so many obj libraries that you'd need to see which fits your needs

I'm trying to make a folder that is ignored on specific build platforms. In a IPreprocessBuildWithReport interface, I'm trying to move Assets/Server to Assets/Editor/TempBuild, then in a IPostprocessBuildWithReport move it back. AssetDatabase.MoveAsset either gives me the error Destination path name does already exist or Destination parent directory does not exist, in addition to an error that says access is denied. I've tried several workarounds with AssetDatabase, but nothing has worked. Does anyone have experience with this?

[gray mural]

No, there is no. And I don't really think you need it

Imagine setting both row and column count to 3 and having more than 9 elements in your group

If you still need it, you may write a script based on the Grid Layout Group to check when the child was added to the GameObject and remove it if needed

Right, let's say you want to have 4 columns and 6 rows.
Set the Fixed Column Count to 4 and manage the other logic via code.

Remove the oldest message just if the current messages count equals to 4 * 6 = 24

[swift falcon]

Hey all!

I'm trying to make a combat system, where the human will attack a pig and it will be knocked back, similar to Super Smash Bros

However, as you can see above, the knocback is not very good

I'm trying to understand the problem however it feels like I just am not handling it properly. I can't type out all the code at the moment until someone asks for a specific area of it, because it's handled by many functions.

this is my damage hitbox script however:

    public GameObject parent;
    public float allowedImmunityTime = 0.4f;
    public AttackHitbox attackHitbox;
    private float immunityTime = 0f;

    [Header("Feedbacks")]
    public MMF_Player DamageFeedback;

    public void Damage(GameObject attacker, Vector2 knockback, float damageAmount){
        if(immunityTime <= 0){
            DamagePopupGenerator.current.CreatePopup(transform.position + new Vector3(Random.Range(-0.5f, 0.5f), Random.Range(-0.5f, 0.5f), 0f), damageAmount.ToString(), Color.red);
            if(attacker.GetComponent<Rigidbody2D>().velocity.normalized.x != 0){
                parent.GetComponent<Rigidbody2D>().AddForce(new Vector2(attacker.GetComponent<Rigidbody2D>().velocity.normalized.x * knockback.x * 2f, attacker.GetComponent<Rigidbody2D>().velocity.normalized.y * knockback.y + knockback.y/4), ForceMode2D.Impulse);
            }
            else{
                parent.GetComponent<Rigidbody2D>().AddForce(new Vector2(Mathf.Sign(attacker.transform.localScale.x) * knockback.x, knockback.y), ForceMode2D.Impulse);
            }
            parent.GetComponent<Animator>().Play("Hit");
            immunityTime = allowedImmunityTime;
            DamageFeedback?.PlayFeedbacks();
            StartCoroutine("ImmunityFrames");
        }
    }

    private IEnumerator ImmunityFrames(){
        while(immunityTime > 0){
            immunityTime -= 0.01f;
            yield return new WaitForSeconds(0.01f);
        }
    }

The main part where we add force is parent.GetComponent<Rigidbody2D>().AddForce(new Vector2(attacker.GetComponent<Rigidbody2D>().velocity.normalized.x * knockback.x * 2f, attacker.GetComponent<Rigidbody2D>().velocity.normalized.y * knockback.y + knockback.y/4), ForceMode2D.Impulse);

Where knockback is a vector2 I define with two arbitary ints that match as a multiplier, and I'm adding the attacker's velocity onto the attack for direction.

[thick terrace]

i feel like the direction vector between the two objects should factor into this too, basing it only on velocity looks weird imo

maybe add some minimum value to the y speed too, your animation looks like a powerful upwards swing and that's not reflected in the code at all

[swift falcon]

yeah! i fixed it up, thank you :)

[open lake]

Hey!
I'm trying to export a .gltf 3d model using Unity's GLTFast library and I came across this on the documentation. Any idea on what this means? I found the two assembly definition files but I dont know where to reference them

[thick terrace]

if your own code isn't inside an assembly definition you've made, you probably don't need to worry about this

[open lake]

I haven't touched assembly definitions before this but Unity says that The type or namespace name 'Export' does not exist in the namespace 'GLTFast' (are you missing an assembly reference?)

[thick terrace]

oh looks like the Export assembly has auto-referenced turned off, so it's not available in the default assembly for whatever reason

if you can't turn that on, then you would need to make your own assembly definition and add it as a reference yeah

[open lake]

Thanks! I just found a github repo of the package and imported that and removed the package manager version. THen I was able to tick the auto reference

[open lake]

Oh, by the way, is there a way for a Unity build to export a gameobject as a prefab so that another build could read it sometime later?

asset bundles, maybe?

[thick terrace]

yeah, asset bundles or addressables, which is asset bundles in a trenchcoat

[open lake]

my addressables journey has been confusing so far

especially with my lack of cloud understanding

[thick terrace]

you can use it without any of the cloud stuff if you don't need it

[open lake]

ok but what about exporting a bundle at runtime? and another build downloading and unpacking it? is that really possible?

if I have a script thats a component on a prefab but the script has been compiled on both builds, then would the references and other stuff transfer over via the prefab without any editor intervention?

[thick terrace]

oh at runtime? not really, prefabs don't exist at runtime

that would be more like a save system

[open lake]

I see

So this is the flow of my application

I import a 3d model, attach a script to it and tweak it a bit and reorder and reposition a few of the children in the 3D model. I have completed my project this far. Now I want to be able to package this gameobject (info about the transform of the GO, its children, the script that I attached to it and its values and references) along with the actual 3D meshes, the .glb . And I want to be able to load this package and get the exact same gameobject

both are builds of the same project

[thick terrace]

what part of this is happening at runtime?

[open lake]

All of it

I know bruteforcing it is an option

or atleast I hope so

put everything in a messy json and reconstruct it

[thick terrace]

you could look at formats other than json, but yeah you'll mostl likely need to serialize the data yourself, asset bundles won't work for this

[open lake]

I see okay

I came across this thing called the binary formatter

Well

[cold parrot]

Don’t use that

[thick terrace]

yeah, it might work but there's various reasons it's not a good idea

[cold parrot]

The reason why it works is the reason why you can’t (shouldn’t) use it

technically you can duplicate a prefab’s yaml and store that to exchange your structures together with the assets but you’d have to basically rebuild the Unity editor’s serializer and asset database for runtime usage.

[open lake]

Hmm I feel like this is almost impossible considering theres models of size of about 60mb involved

[open lake]

oh

[cold parrot]

It’s 100% not what unity is designed for though

[open lake]

agreed

[thick terrace]

BinaryWriter/BinaryReader are decent but you'd need to write a lot of the boilerplate serialization stuff yourself, i'd check out maybe protobuf of flatbuffers or one of those libraries

[cold parrot]

You will be fighting the engine at every turn

[thick terrace]

i use MessagePack but it's kind of fiddly to set up

[fast timber]

I have a lot of errors of this form:

The .meta file *** does not have a valid GUID and its corresponding Asset file will be ignored. If this file is not malformed, please add a GUID, or delete the .meta file and it will be recreated correctly

Can I somehow automatically tell unity to remove all meta files with invalid guids, but keep the rest?

[cold parrot]

all ‘safe’ serialization is terribly annoying to use 😄

[open lake]

sorry if this sounds annoying but 😅
where would one go about beginning the serialization process

[cold parrot]

What’s typically done is embedding an interpreted language for runtime execution

and using that to do all of your asset/prefab export/import

[thick terrace]

i'm not sure how adding an interpreter helps with that 😅

[cold parrot]

that works with regular unity asset bundles since Unity treats it all as data, and this would allow you to include code in your assets

[cold parrot]

No scripts can be added via assetbundles

[thick terrace]

oh for scripts, yeah, if you need to add new scripts in a bundle

idk if chipe needed that

if you just need to save which existing scripts from the base game are on a prefab, that can all be done with any serialization library

[open lake]

yup

[cold parrot]

an interpreted language, maybe a DSL, would just be a replacement for a complicated API that these assets would need to use declaratively

It’s all a big yuck to develop though 🙃

[thick terrace]

there's lots of answers to this but i guess at some point you have to have a method like void Serialize(GameObject instance, Stream output) and the rest is up to whatever serialization format you're using haha

[cold parrot]

If you were using an engine where the# editor and runtime are the same app, it’d be a breeze to implement

[open lake]

is that why debug gizmos dont work in builds?

[cold parrot]

yes

But there are assets for that. You can still draw your own, but not through the builtin API

[open lake]

hmm I'll report to you once I get there

[fast timber]

I am getting errors of the form

The referenced script is missing on Shooter Spawner (index 2 in components list)

However, I do not have a gameobject called Shooter Spawner in my scene

does anyone know how I could find the GO the error is talking about?

[gray mural]

Isn't it a component?

"index 2 in components list"

[fast timber]

Yes but a component on some game object

or actually I don't know

[gray mural]

Well, yeah, you said "I do not have a gameobject called Shooter Spawner"

[fast timber]

if shooter spawner refers to the GO name or component name

[gray mural]

Well, this is definitely not a build-in component

[fast timber]

Yes you are right, but in either case I'm not finding the corresponding GO :/

[fast timber]

yes haha

[gray mural]

You have a ShooterSpawner script. Find its references

[fast timber]

Yes thats what I tried

but here is riders find-anything results - empty

let me maybe try find

[gray mural]

I don't use Rider. Does it have "asset references" written above its class' name, as shown in the image I've sent?

And how don't you know about your own scripts? Do you have so many of them?

[fast timber]

But no, there is no single file which has the word ShooterSpawner inside of it:

/Assets$ find . -type f -name "*.cs" -exec grep -l "ShooterSpawner" {} +

this returns nothing and should return all files

[fast timber]

yeah ofc its quite a large project, I don't have them all in my head haha

[fast timber]

but if neither find nor rider are able to find any file with ShooterSpawner in it, I don't think there is any file

[gray mural]

Does this have the call stack?

You may also try finding it in Unity Assets

[fast timber]

Ah actually, the error comes from a package I have installed

I'll ask the support there, maybe they are still using some old files or something

[gray mural]

If it's a package you have installed, you can find the scripts in Packages.

[fast timber]

I do not think its actually a GO. I now found more error messages of the form

The referenced script on this Behaviour (Game Object 'Shooter Spawner') is missing!
UnityEngine.Object:Instantiate<UnityEngine.GameObject> (UnityEngine.GameObject)
Rukhanka.Hybrid.AnimatorControllerBaker:ConvertAllControllerAnimations (UnityEngine.AnimationClip[],UnityEngine.Animator) (at ./Packages/com.rk.rukhanka/Rukhanka.Hybrid/AnimatorControllerBaker.cs:550)

I think it just has some old GO referenced somewhere and I do not fully know where, I'll find it though

Thank you for the help!

[gray mural]

Right, that's probably the package's problem then

[grizzled dune]

Good afternoon everyone
I have a question regarding in app purchases
So I'm pretty sure most of you know about Lucky Patcher, if not it's an app that bypasses your IAP and basically gives you free money
Is there a way to prevent Lucky patcher to not give free stuff and bypass your IAP? An example is Future Fight, the game is built on Unity however they don't let Lucky patcher bypass their IAP

[leaden ice]

Not really a Unity question. I googled it: https://stackoverflow.com/questions/13445598/lucky-patcher-how-can-i-protect-from-it

[grizzled dune]

I apologise if it's not a unity question
But only reason I asked here is because I use unity to build my games and what not

[leaden ice]

Do note however with something like this it's a never ending and ultimately losing battle

Since the user physically owns their own device there's ultimately little you can do to prevent them from controlling the software running on the device, if they are sufficiently motivated

If it's a network enabled game you can get away with judicious validation and ownership of the data stores keeping track of user items and currency etc

[grizzled dune]

I'm more of targeting the users who doesn't have knowledge on how to bypass such things without the use of lucky patcher, hence the majority of users

[grizzled dune]

I'd make it a network enabled game but however I have little to no knowledge on how that works, I'm still studying it and once I do know how to do it I'll make it a network game

[thick terrace]

if enough people care, it only takes one person to write a new patcher for your game, then it's just as easy for everyone else

[chilly surge]

Someone can always make a cracked version of your app with everything purchased.

I have no evidence to back this claim up, but if you are making a single player game, people who are desperate enough to do these kinds of hacks, aren't likely the ones to ever purchase anything anyways.

[sturdy kindle]

Question about managing sound effects:

I began managing my sound effect files by creating an Audio Manager script that's applied to a game object which stores a list of my audio sources. I then reference to a specific file within other objects as needed.

I've read this may become an issue with memory as I'm loading all the files into the game, including the ones that may not be used in a specific scene.

Would it be better to apply the audio files to the objects that use them?

[fleet furnace]

Dont try to optimize something that is not an issue yet. Release first then solve this 😉

[opaque forge]

Hello I'm trying to instantiate objects along specific positions and with correct rotation in script, but the pivot position of that object is on the corner instead of the center so when instantiated with a specific rotation like 90 degrees for instance, it rotates around the pivot point, therefore shifting the actual position. I tried to instantiate it in a parent to solve the problem but it still rotates around the pivot point. Can anyone point me in the direction to solve this issue

  parent.transform.position = position;
  Bounds bound = GetPrefabBounds(building[0]);
  Vector3 pivotOffset = position + new Vector3(bound.size.x / 2.0f, 0, bound.size.z / 2.0f);

  Instantiate(building[0], pivotOffset, Quaternion.Euler(0, Yrotation, 0), parent.transform);
  parent.transform.DetachChildren();
  Destroy(parent);

[open lake]

Hey I'm back

[leaden ice]

Why not just fix your prefab's pivot

[opaque forge]

Is it hard to do?

I have a huge amount of them and tought it would take a lot of time

[open lake]

I managed to build somewhat of a serializer for a gameobject and I've covered Mesh filter and transform components @cold parrot @thick terrace
But now the problem is parsing through all the children in the GO and then instantiating then all at once is taking a toll on my performance. How do I fix this?

Also stuck on materials

https://gist.github.com/hemanth2004/e79780405f4b49a0b5d58edea9cee207

This is what I've come up with but the material part is still very errory

[latent latch]

load screen and cache em

[fleet furnace]

Well unless you fix the pivot points then you have to be able to specify the point you want to rotate around specifically.
Do you know around which point you want to rotate it about? Because if you do then just specify the axis in this method and you are done https://docs.unity3d.com/ScriptReference/Transform.RotateAround.html

[thick terrace]

unity prefabs have the advantage of being deserialized on a background thread so you could look at doing the same thing, otherwise if you can't cover it up with a loading screen, you could write it as a coroutine and yield between the expensive operations and/or every x elapsed milliseconds to split the operation over several frames

[sturdy kindle]

The shifting problem happens because the rotation is being applied after translating for the offset, which still causes rotation around the original pivot point of the object.

[open lake]

It takes less than 2 seconds for a model with 1.5M vertices and 7 materials to be recreated. apparently mesh serialization was what took so long, Holo-Lens put out a samp,e unity project where they used a mesh serializer which was what reduced the 2 minute load time to 2 seconds 😁

[heady iris]

You must search by GUID, not name

Unity does not care about asset names.

[fast timber]

I found the error now. It was actually not a component, but gameobjects of that name

[heady iris]

I grep for GUIDs fairly often. It's more reliable than Unity's own "find references"...

usually when i'm seeing if i can delete an asset

[fast timber]

I found them using find/grep by searching all files for Shooter Spawner instead of ShooterSpawner

they were in a .prefab file

[heady iris]

Ah, I see!

[fast timber]

then I checked that prefab and saw that it has deactivated child gameobjects which reference those scripts

[versed spade]

I have many areas in my code that require themselves to be updated a little bit to accomadate whenever I had a new weapon type. Are there are programmer techniques or VSC extension that will make it easier to track these. They will be in multiple different files

[chilly surge]

What kind of changes?

Ideally, you would write code in a way that the compiler does it for you, by causing compile errors unless you have properly implemented things.

[placid summit]

Has anyone done an inverted mask for UGUI? struggling with examples

[heady iris]

alternatively, the design needs to be changed so that new kinds of weapons don't require you to rewrite so much existing code!

the whole open-closed principle

Is there a better way to detect that the game has changed screens than constantly comparing the current list of resolutions to an old list of resolutions?

I need to update my settings menu when this happens

[heady iris]

but this is emitting a lot of garbage

I'm pretty sure Displays.onDisplaysUpdated does not fire when this happens

(it's not even in the documentation!)

[versed spade]

Basically I have 3 weapon types: Repeater, Ballistics, Cannon. If I add another called... Beam it will not choose the right set of stats until I manually update weapon logic to include it

[chilly surge]

How are your code currently structured? That sounds like a design issue.

One way to do it is to have the stats on the weapons themselves, eg a Weapon base class or an IWeapon interface that has Stats property.
Whatever that needs the stats would just do currentWeapon.Stats to get it, it would not involve updating any code.

[versed spade]

Probably I'll thread the code here:

Or not clyde says no

using System;
using System.Collections;
using System.Collections.Generic;
using Unity.VisualScripting;
using UnityEngine;

[CreateAssetMenu(fileName = "New Weapon", menuName = "Weapon")]
public class WeaponObject : ScriptableObject

    [Tooltip("Make sure the model is a PNG and has been set to Point Rendering")]
    public Sprite model;
    public new string name;
    public string description;

    public enum weaponType { Nothing, Repeater, Ballistic, Cannon }

    [Tooltip("Here you can specify the weapon type which will change the stats it uses.")]
    [SerializeReference]
    public weaponType type;


    [Header("Weapon Stats")]
    
    public RepeaterStats repeaterStats;
    public BallisticStats ballisticStats;
    public CannonStats cannonStats;
   
    #endregion
}

#region Weapon Variables

[System.Serializable]
public class RepeaterStats
{
    public int maxChargedAmmo;
    public float laserDamage;
    public float lasersPerMinute;
    public float dropoffDistance;
    public float chargingSpeed;
    public GameObject projectile;
}

[System.Serializable]
public class BallisticStats
{
    public int maxBallisticAmmo;
    public float bulletSpread;
    public float bulletDamage;
    public float bulletsPerMinute;

}

[System.Serializable]
public class CannonStats
{
    public int maxCannonShells;
    public float shellDamage;
    public float reloadTime;
    public GameObject projectile;

#endregion

This is the code for the weaponObject itself. Each class is belonging to a different weaponType

    void Start()
    {
        playerControls = new PlayerInputs();
        playerControls.Enable();
        weaponType = weaponData.type.ToString();

        // Make changes to this as new weapons are added
        switch (weaponType)
        {
            case "Repeater":
                fireRate = 60 / weaponData.repeaterStats.lasersPerMinute;
                break;
            case "Cannon":
                fireRate = weaponData.cannonStats.reloadTime;
                break;
            case "Ballistic":
                fireRate = 60 / weaponData.ballisticStats.bulletsPerMinute;
                break;
        }

Display.main doesn't change when you move the game from one screen to another, so that doesn't help.

Ok, I remember discord had some sort of in-app code block thing that shrunk it. Is it gone or am I using it wrong?

that's when you send a file

[heady iris]

use a paste site

[fervent furnace]

to the one who delete their question
i think it is nearly impossible to get a non axis-aligned bounding box (call it NAABB below
consider a triangle, there is only one AABB of it, but for NAABB you can have 3 (if you make the NAABB aligns one of its side)

[grand compass]

So, I'm screwed, sad
Thanks for the info

[heady iris]

you can compute a bounding box in an object's local space

[fervent furnace]

ofc you can somehow define its "major axis" then for all other vertices, get their distances to the axis and bound it

ah, compute (get) the AABB in local space then rotate it

[grand compass]

I'll try to think about your possible solutions. Thank you so much, both of you!

[heady iris]

Ah, I can get Screen.mainWindowDisplayInfo, which does change when the window moves from screen to screen.

and I can then check if the height/width/refresh rate/name changed

this allegedly produces no garbage

I have a missle and a mesh with other objects like trees and stuff. I want the rocket to rotate to avoid the obstacles and mesh. However this code just doesnt work and im confused why

[heady iris]

is _rotateSpeed non-zero?

if it is serialized, look in the inspector

[edgy stump]

Anyone?

[heady iris]

ah, your rotation is backwards

do transform.rotation * ...

Q1 * Q2 is the result of applying Q1 followed by Q2

[vapid lynx]

huh?

Quaternion avoidanceRotation = Quaternion.FromToRotation(transform.forward, -surfaceNormal) * transform.rotation;

oh this line?

[heady iris]

Quaternion multiplication is not commutative: A * B != B * A
